Abstract
Abstract.The phenomenon was understood as the basic element to constitute knowledge in this study,
where the granular structure was taken as the basic structure of phenomenon formalized representation.
Based on the isomorphism between formal concept analysis and rough set theory, the granular structure
model was established in conceptual category of phenomenon, and the correlation among concept categories
was given as well as correlation distance, proving that the concept element space induced by correlation
distance \u0398 was a metrizable space. Based on the conclusions in this study, the knowledge representation
model can be established more completely than conceptual model in semantic description, providing a basis
for phenomenon formalization research by using the topologic method.
